Working capital finance vs a business overdraft

An overdraft and a short-duration working-capital facility can both bridge a cash-flow gap. They are not the same tool, and using the wrong one is expensive in time as much as money.

An overdraft is a standing buffer

An overdraft sits against your trading account and lets you dip below zero up to a limit. It is useful for small, frequent, unpredictable swings. The limit is usually modest, it can take weeks to arrange or increase, and the bank can review or reduce it — often when you most want it there.

Working-capital finance is for a defined job

A short-duration facility is drawn for a specific, near-term purpose — a stock buy, a contract you need to mobilise, a receivable you're bridging — and repaid over a defined term. Because it is structured around one requirement, it can be sized to the opportunity and decided quickly.

How to choose

• Small, recurring, unpredictable swings → an overdraft buffer usually fits.
• A specific, larger, time-sensitive requirement → short-duration working capital is usually the better match.
• You need a decision in days, not weeks → speed favours a purpose-built facility.

The right answer depends on your business. If you're weighing a specific requirement and the timing is tight, it's worth getting an indicative read before you commit either way.
